“…Instead, charge effects have so affected the bands that there is no substantial d-band character at or within kT of EF • A similar situation appears to occur in dilute alloys of Ni in Cu [235]. Knight shift results have been obtained for both transition metal sites and nonmagnetic sites in itinerant ferromagnets [236,237,14] such as ZrZn2. These systems are characterized by having ferromagnetic saturation moments, qs, which are small compared with effective moments, qc, associated with the paramag· netic susceptibility.…”

“…The difficulty of obtaining solid state 91Zr NMR powder spectra for anything but rigorously cubic compounds (e.g. ZrZn, [2], ZrCo [3] and ZrC [3]) indicates that the coupling is not negligible. The quadrupole moment for 91Zr (derived from atomic beam resonance methods) is -0.206 x loTz8 m2 [4].…”

The first measurement of 91Zr nuclear quadrupole coupling in a solid is reported. The nuclear quadrupole coupling constant (e2qQ/h) and chemical shift anisotropy ( sigma ax) for 91Zr, and the chemical shift anisotropy for 29Si, have been determined for zircon (ZrSiO4) from high-field NMR single-crystal rotation patterns. A striking variation of 91Zr linewidth with crystal orientation in the field was observed and explained in terms of local variations in the (001) tetragonal axis orientation due to crystal mosaic structure as well as a distribution of local electric-field gradients due to defects.

“…They have confirmed the itinerant nature of spin polarization, as the latter is delocalized along the network of Zr atoms with the maximum polarization at the middle of Z-Zr bonds. The existence of a magnetic short-range order in ZrZn 2 however has been confirmed by nuclear magnetic resonance (NMR) on the 91 Zr nuclei [18][19][20].…”

Hyperfine field assessment of the magnetic structure ofZrZn2

et al. 2015

Time differential perturbed angular γγ-correlation (TDPAC) method on 111 Cd nuclei probes inserted in ZrZn1.9 is used to measure the magnetic hyperfine fields (MHFs) at Zr and Zn sites and the electric field gradient (EFG) Vzz at Zn sites as a function of temperature at various pressures and as a function of pressure at the temperature 4 K. Our data indicate that the local magnetic moment of Zr in the magnetically ordered state is substantially larger than its value obtained from the macroscopic measurements and that there is also an induced magnetic moment at the Zn site. We conclude that ZrZn2 is not a simple ferromagnet and discuss a possible type of its magnetic ordering.
